The first major snowstorm of 2014 left between four and eight inches of snow on the ground overnight Thursday. As crews worked to clear the roads, and the region recovered from the snowfall, frigid temperatures began to set in, leaving South Jersey with a very cold Saturday prediction.

As the temperatures fall, moisture on the roads from the previous snow storm can freeze, leaving potentially hazardous conditions.

Jeff Ridgway, the director of Salem County’s Public Works Department, was out with his crews all night Thursday into Friday — and for most of Friday morning and afternoon — clearing snow and salting the streets throughout the county.

Despite their work, there’s still a possibility of icy conditions. The high winds then cause the light, fluffy snow to cover icy roads.

“Always count on ice being below that drift,” Ridgway said. “I would suggest people stay inside. If they have to go out, make sure there’s a lot of space between them and other cars.”

East Greenwich Police Chief Barry Jenkins agrees.

“Just take your time,” he said. “Give yourself extra time to get where you’re going and stay off the roads if you can.”

Below freezing conditions and high winds also present a concern when it comes to the homeless and those who live alone, especially the elderly.

Camden County has issued “Code Blue” alerts through Saturday morning for frigid temperatures. A Code Blue advisory is declared when severe weather hits municipalities with homeless populations or transient populations.

“With treacherous weather already settled into the area and getting worse by the hour, we need everyone to be sheltered and out of the elements,” Camden County Freeholder Carmen Rodriguez said in a written statement.

Bridgeton Mayor Albert Kelly spent Thursday evening at one of the city’s warming shelters making sure those without homes were able to have a warm place to spend the night.

About 35 people came in that evening, he said, and the center will continue to be open through Saturday.

Those without homes, or without heat in these conditions, are encouraged to contact their local social services department for placement or assistance. Those with elderly neighbors who live alone are asked to check on them if possible.

In Gloucester County, social services can be reached at 856-852-9200 or through the Gloucester County Emergency Helpline at 856-256-2283.

In Salem County, social services can be reached at 856-299-7200 and in Cumberland County, social service’s number is 856-691-4600. Camden County’s Social Services can be reached at 856-225-8800.

Cold weather and high winds can also damage utility lines, leaving customers susceptible to power outages and loss of heat. Local utility companies have prepared for the current conditions and have not seen a great deal of customers affected up to this point.

Less than a dozen Atlantic City Electric customers reported outages in South Jersey as of Friday afternoon and the company is standing by with trucks in case more occur.

"We are monitoring the effects the drop in temperatures may have,” said Lindel Jones, a spokeswoman for the company. “We are prepared with crews ready, but as of now we are not seeing a need.”

If outages do occur, customers are asked to call utility companies directly at the numbers below:
